IMPROVEMENT IN PLOWS.

kann- The Schedule referred to ln these Letters Patent and making part of the same.

To all whom 'it 'ma/y concern Be it known that I, O. OSBOBN, of Trumansburg, in the county of Tompkins, and in the State of New York, have invented certain new and useful Improvements in Plows; and do hereby declare that the following is a full, clear, andv exact description thereof,

' reference being had to the accompanying drawings, and

Figure 2 is a rearview; with the plow removed ,showing the mode of raisin g and lowering the furrow-wheel.

A represents a beam of suitable dimensions, across the centre of which is placed a cross-beam, B.

To one end of this cross-beam is secured the axle a, on which the smaller, or land-wheel C, is placed.

To the other end of the cross-beam B is secured a vertical plate, b, on or around which a metal box, D, slides, said sliding box being provided with an axle, c, on which the larger, or furrow-wheel E, is placed;

The rear side of the box D is provided with cogs, as seen in iig. 2, which gear into a cam, F, having cogs on its periphery; aud;said cam-being provided with a handle or lever, d, it will readily be seen that the metal box D, with the axle c and large wheel E, can be raise or lowered at will.

, The handle d passes through a slotted and curved plate, e, on the cross-bar B, and maybe held, by a suitable device, at any point desired.

The tongue G is pivoted at the front end of the beam A, and has, at its rear end, a handle, or lever, H, placedl at suitable angle tothe same, extending toward the rear and upward.

The handle, or lever H, passes through a slotted plate, f, secured to the front side of the standard I, which is placed at right angles from the beam A, just in front of the cross-beam B.

The plate fis notched at intervals, as shown in iig. 2, so that a spring, g, which is attached to the handle H, may pass into said notches, and thus hold thetong'ue G in any position desired, whereby the, depth of the furrow is regulated, for it will be seen that, by lowering the lever H, the tongue G is raised, and the plowl carriage lowered, and, by raising the lever, the plow-4 carriage is raised.-

On .the side of the beam A, in rear of the cross-beam B, a plate, h., is secured.

This plate has three'curved slots, the two outer ones of which are used to regulate the position of the plate on the beam, as the plate is secured by screws passing through said slots into the beam.

The centre slot isuscd to allow a plate, k, which sup-l ports the plow-beam, to slide up and down, the said plate k being held on the outer side of the former plate h, by means of screw-bolts i t, which pass through the centre slot, and nuts placed on the ends of the same.

The plow-beam J passes through a loop, m, on the 4outer side of the plate k, and its front end is pivoted to a bar, K, projecting downward from the beam A, a suitable distance in rear of the tongue G.

To the inner handle of the plow is secured a chain, n, which passes over a pulley, o, in the rear end of the beam A, and up to a crank, p, at the upper end ofthe standard I, so that by turning the crank p, the plow may be raised up out of the ground, the plate k sliding .on .the plate h.

A seat, K, is placed for the driver, at a suitable point on the cross-beam B, that he may have the lever H, handle d, and crank p, within his reach.

On the cross-beam B, near the driveiis seat, is also pivoted a lever, L, which operates'a bar, M.

This bar is pivoted to the under side ofthe beam A, and has a spring-bar, r, attached to its rear end, which can be thrown against the plow-handle, to steady it, and hold the plow down in hard and stony ground.

Having thus fully described my invention,

What I claim as new, and desire to secure by Let ters Patent, is-

1. Providing the tongue G with a lever, H, having a spring, g, and passing through the slotted and notched plate j, for the purpose of raising or lowering the tongue, and holding it in any position desired, substantially as shown and described. Y

2. The arrangement of the plate b, cogged sliding box D, with its axle c, cogged cam F, and handle d, all constructed and operating substantially as and for the purposes herein set forth.

3. The arrangement, on a plow-carriage, of the slotted plate h, sliding plate k, and loop m, for the purpose of holding the plow-beam, substantially as shown and de-l scribed.

4. The arrangement of the lever- L, arm M, and spring-bar lr, for the purpose of' steadying the plow, substantially as herein set forth.

In testimony that I claim the foregoing, I have here# unto set my hand, this 5th day of January, 1869.
